Thank you for all the inputs.
Actually, I am reluctant to do the update line by line.
I plan to use a shell script to
. replace all characters such as ' to \'
. update each line to insert into
. call "-c query " load the file into db
In java, call this shell script, after data populated into tables, will
do other data comparison based on this table then.
